main relay
It''s near the Trai coil area and has two plugs. One has four wires and the other two wires. The two wire one is the ground and power for pulling it in
Pull that plug apart with the key to On and you should feel/hear the relay pull in if you put the plug back on the relay.
IF you have the key to ON and check either of the coil assy for power on their black/yellow wire and have it, that proves one circuit thru the Main Relay is good. Or as an alternative, crank the engine and see if the tach needle makes little movements. If it does, that circuit thru the Main Relay is good.
Of you have the key to ON and go to any of the solenoids on the vacuum rack, and have 12vdc on the black/white wire of those solenoid plugs, then the OTHER circuit in the Main Relay is good.
